Best PDF converters

Perhaps you want to create a PDF file? Or maybe you want to make changes to an already created file? That’s why you need PDF converters. These programs can help you convert your PDF to flipbook and many different types of files, to make them look better on any computer or mobile device.

In this article, we’ll explain what is the PDF file format, what is a PDF converter and describe some of the best free PDF converter apps online!

What are PDF files?

Editing PDF file for free


If you have prepared a text document in Word formats like RTF or DOCX, the way it appears on the screen can depend on a number of factors. If the other person doesn’t have the specific fonts installed or is using a different application like Libre Office or macOS Preview, the document will look different than you’d expect.

This is why PDF files have been created. Thanks to PDF format, your text is converted to curves, which display the same on every computer. However, since the text is read both as text and as an image, it is not possible to make changes to a PDF file without completely rebuilding the file. PDF format means that you cannot change the content of the document.


What is a PDF converter?

The PDF converter is a software able to perform this task. As the name implies, it converts to PDF all sorts of files: DOC, XLS, or RTF. Some can also convert PDFs, to an editable format. With such programs, you can, for example, make corrections to your CV or “pull” some graphics from a closed PDF document. An online PDF converter works in your browser, pulling content from data it gains when you upload files to the server.

You can also convert your PDF with an online flipbook maker to HTML-5-based flipbooks, keeping your data secure on specially designed servers. Your PDF can be displayed easily in a browser on all operating systems. Besides these features, you can add videos into your PDF file, add photo galleries and much more! It gives your PDF a new, more eye-pleasing look that can easily make it more engaging for the receivers of your converted document, like the one displayed below.

What interactive features should a good PDF converter have?

A good online pdf converter works not just to create files in the PDF format, but it should also have additional features. Publuu lets you convert files in the PDF file format, and add multimedia capabilities. Some of these interactive elements can be adding photo galleries or adding videos to your PDF.

When you find out how interactive PDFs are presented and you replace your documents that you send on a daily-basis. Adding interactive elements will be a sure way to make your PDFs stand out from a sea of similar files and make your readers engage more.


What should a good PDF converter have?

Read on to find out about the best PDF converters and the advantages and disadvantages of each, so you can make an informed decision.

Here are a number of criteria we have taken into account in preparing the list of the best PDF converter apps:

  • Multiple output file formats: a good-quality free PDF converter should provide a variety of output and input file formats. This includes commonly used formats such as Microsoft Office documents, images, text, and HTML, as well as rarer formats like EPUB, MOBI, or DJVU. This ensures that users can convert PDF files to the desired format for their specific needs, as well as convert to PDF.

  • OCR capability: OCR, or optical character recognition, is a key feature of the PDF converter. Many free programs do not have this feature. It allows images to be scanned and converted into editable documents. This is particularly useful for scanned PDF files that may contain text saved as graphics – for example, document scans. Libraries and archives should try to convert PDFs using the OCR features.

  • Batch conversion: the batch conversion feature allows users to process multiple PDF files simultaneously, saving time and effort. This is particularly useful for users who have a large number of PDF documents that need to be converted: for example, people working with invoices. Often free versions only allow up to about 5 files to be converted at a time.

  • High conversion speed: The faster the program, the more time you save. A high-speed online PDF converter enables users to convert PDF files quickly and efficiently without waiting long for the process to complete.

  • High-quality conversion: High-quality conversion ensures that the original format of the PDF files is preserved. This means that the text, images, and other elements of the PDF file will be preserved and the final result will look exactly like the original. This is not always possible, especially with online pdf converter apps!

  • User-friendliness: User-friendliness or ease of use is an important feature of a free PDF converter. It refers to how easily users can navigate and use the software, without facing challenges or obstacles. A user-friendly PDF converter makes the conversion process simple and straightforward so that users can carry it out efficiently and effectively.

  • Additional features: A lot of extras matter when you convert files. For instance, Publuu lets you embed video content in their flipbook and takes care of the necessary file transfers. If a PDF converter goes the extra mile to provide you with a good experience, it’s also worth thinking of!
